AttributeError: Module 'PyQt5' has no attribute '__version__'

Question

I was trying to warp a python file to an .exe file. But with these two lines, I encountered this problem.

import cv2
exit()

If I just print something like: print('dsfdsfs'), then it can be wrapped to an .exe successfully.

My environment:
win10
pyinstaller 5.0.dev0
opencv-python 4.5.2.54
pyqt 5.9.2

And I was using anaconda prompt to do so.

I'm seeing the same issue. pip install PyQt5 errored out... Pyinstaller team needs some serious help. Reverting back to previous version of Pyinstaller that works on my system.

Answer 2

Unfortunately it seems that PyQt5 module on Anaconda is busted and missing various files that might be required by other modules, in my case PySimpleGui. The absolute easiest solution is to create a brand new environment, fortunately this is quite easy in anaconda, and pip install pyqt5. This should resolve any issues. Also install the rest of your packages and you should be good to go!

Answer 3

After loosing too many hours on this I updated PyInstaller and voilà it worked.

Answer 4

I solved this problem by manually adding __version__ = "5.15.4" to venv/Lib/site-packages/PyQt5/__init__.py where venv is a virtual environment in which PyQt5 is installed.

Before:

...
# 
# This file is provided AS IS with NO WARRANTY OF ANY KIND, INCLUDING THE
# WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.


# Support PyQt5 sub-packages that have been created by setuptools.
__path__ = __import__('pkgutil').extend_path(__path__, __name__)

def find_qt():
...

After:

...
# 
# This file is provided AS IS with NO WARRANTY OF ANY KIND, INCLUDING THE
# WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.


# Support PyQt5 sub-packages that have been created by setuptools.
__path__ = __import__('pkgutil').extend_path(__path__, __name__)
__version__ = "5.15.4"

def find_qt():
...

Answer 5

I'm using pyinstaller and anaconda prompt and found the same issue, to solve it you must

pip install PyQt5 --user --use-feature=2020-resolver

and then run pyinstaller again.

Answer 6

I figured out a fix. When you convert your .py file to .exe with auto-py-to-exe you have to click "advanced" then add "hidden-imports" there you add the things you import in your .py file, for example, my .py file imports "sounddevice" "numpy" and "os", so I add all of those into the "hidden-imports" in auto-py-to-exe" I hope this helped - here is a picture: example

Answer 7

Try using "pip install PyQt5" and then run again
